Deploying Anchore Enterprise on OpenShift

This document will walkthrough the deployment of Anchore Enterprise on an OpenShift Kubernetes Distribution (OKD) 3.11 cluster and expose it on the public internet.

Note: While this document walks through deploying on OKD 3.11, it has been successfully deployed and tested on OpenShift 4.2.4 and 4.2.7.

Prerequisites

• A running OpenShift Kubernetes Distribution (OKD) 3.11 cluster. Read more about the installation requirements here.
  • Note: If deploying to a running OpenShift 4.2.4+ cluster, read more about the installation requirements here.
• Helm client and server installed and configured with your cluster.
• AnchoreCTL installed on local host.

Anchore Helm Chart

Anchore maintains a Helm chart to simplify the software deployment process. An Anchore Enterprise installation of the chart will include the following:

• Anchore Enterprise Software
• PostgreSQL (13)
• Redis 4

To make the necessary configurations to the Helm chart, create a custom anchore_values.yaml file and reference it during deployment. There are many options for configuration with Anchore, this document is intended to cover the minimum required changes to successfully deploy Anchore Enterprise on OKD 3.11.

OpenShift Configurations

Create a new project

Create a new project called anchore-enterprise:

oc new-project anchore-enterprise

Create secrets

Two secrets are required for an Anchore Enterprise deployment.

Create a secret for the license file: oc create secret generic anchore-enterprise-license --from-file=license.yaml=license.yaml

Create a secret for pulling the images: oc create secret docker-registry anchore-enterprise-pullcreds --docker-server=docker.io --docker-username=<username> --docker-password=<password> --docker-email=<email>

Verify these secrets are in the correct namespace: anchore-enterprise

oc describe secret <secret-name>

Link ImagePullSecret

Link the above Docker registry secret to the default service account:

oc secrets link default anchore-enterprise-pullcreds --for=pull --namespace=anchore-enterprise

Verify this by running the following:

oc describe sa

Note: Validate your OpenShift SCC. Based on the security constraints of your environment, you may need to change SCC. oc adm policy add-scc-to-user anyuid -z default

Anchore Configurations

Create a custom anchore_values.yaml file for your Anchore Enterprise deployment:

# NOTE: This is not a production ready values file for an openshift deployment.

securityContext:
  fsGroup: null
  runAsGroup: null
  runAsUser: null
feeds:
  securityContext:
    fsGroup: null
    runAsGroup: null
    runAsUser: null
  feeds-db:
    primary:
      containerSecurityContext:
        enabled: false
      podSecurityContext:
        enabled: false
postgresql:
  primary:
    containerSecurityContext:
      enabled: false
    podSecurityContext:
      enabled: false
ui-redis:
  master:
    podSecurityContext:
      enabled: false
    containerSecurityContext:
      enabled: false

Install software

Run the following command to install the software:

helm repo add anchore https://charts.anchore.io helm install anchore -f values.yaml anchore/enterprise

It will take the system several minutes to bootstrap. You can checks on the status of the pods by running oc get pods:

$ oc get pods

Create route objects

Create two route object in the OpenShift console to expose the UI and API services on the public internet:

Note: Route configuration is optional. It is used throughout this guide to expose the Anchore deployment on the public internet.

API Route

UI Route

Routes

Verify by navigating to the anchore-enterprise-ui route hostname:

Anchore System

Verify API route hostname with AnchoreCTL:

Note: Read more on Deploying AnchoreCTL

# ANCHORECTL_URL=http://anchore-engine-anchore-enterprise.apps.54.84.147.202.nip.io ANCHORECTL_USERNAME=admin ANCHORECTL_PASSWORD=foobar anchorectl system status
...
...

Anchore Feeds

It can take some time to fetch all of the vulnerability feeds from the upstream data sources. Check on the status of feeds with AnchoreCTL:

# ANCHORECTL_URL=http://anchore-engine-anchore-enterprise.apps.54.84.147.202.nip.io ANCHORECTL_USERNAME=admin ANCHORECTL_PASSWORD=foobar anchorectl feed list
...
...

Note: It is not uncommon for the above command to return a: [] as the initial feed sync occurs.

Once the vulnerability feed sync is complete, Anchore can begin to return vulnerability results on analyzed images. Please continue to the Usage section of our documentation for more information.
